摘要
研究了在超声波辅助作用下的兔皮铬鞣过程,分别考察了在不同鞣液浓度,处理时间,不同频率下的超声波对样品中铬鞣剂的渗透速度及收缩温度的影响。结果表明,短时间的超声处理即可有效加快铬鞣剂的渗透,且超声波对铬鞣剂在兔皮皮板内的渗透扩散及结合的促进作用主要表现在经超声处理后的前4 h。但超声波的作用并没有随着超声时间的延长而一直保持增加,且超声波作用并不能提高兔皮与铬鞣剂的结合总量。此外,在反应的前4 h内,较低频率(45 kHz)超声波对铬鞣效果的增强更为明显。
The effect of power ultrasound on chrome tanning of rabbit skin was investigated in this paper. The influence of chrome tanning liquid concentration, reaction time and the intensity of the ultrasonic wave on the velocity of permeability and shrinking temperature （Ts） were experimented respectively. The results indicated that a short-time reaction with ul- trasonic wave could effectively increase the penetrating and binding rate of chrome in the beginning of the tanning pro- cess, but the total amount of the combined chrome could not be increased over time. Furthermore, it was found that under the use of low-frequency uhrasonic, the ultrasonic of 45 kHz could improve the tanning effect the most in the first 4 h.
